(Probably silly) OpenGL/XCode question

Howdy folks.. this is probably a silly question but its got me stumped..

I am new to Carbon/OpenGL/XCode, but know C/C++ pretty well (at least - I hope I do, Im employed as a C programmer)

I am following the NeHe tutorials, using the base Carbon Application as a template (thats been mostly hacked out).

I have both OpenGL and GLUT included in the Frameworks and Libraries section of XCode.

I managed to get a window to display, that went fine. When I went to draw things (triangles and quads), I get the following linking error (with ZeroLink turned on the error occurs at runtime rather than link time)

Code:

Undefined symbols: _glvertex3f

I'm sure its just something silly I have missed.. anyone have any advice?
